b5229a0b3e movsub_bsf: Fix mov2textsub regression 
The mov flavour of timed text uses the first two bytes of the packet as
a length field. And up until 11bef2fe said length field has been read
correctly in the mov2textsub bsf. But since then the next two bytes are
read as if they were the length field. This is fixed in this commit.

7c2dd1f969 avcodec/cuviddec: improve progressive frame detection 
There are 2 types of problems when using adaptive deinterlace with cuvid:

1. Sometimes, in the middle of transcoding, cuvid outputs frames with visible horizontal lines (as though weave deinterlace method was chosen);
2. Occasionally, on scene changes, cuvid outputs a wrong frame, which should have been shown several seconds before (as if the frame was assigned some wrong PTS value).

The reason is that sometimes CUVIDPARSERDISPINFO has property progressive_frame equal to 1 with interlaced videos.
In order to fix the problem we should check if the video is interlaced or progressive in the beginning of a video sequence (cuvid_handle_video_sequence).
And then we just use this information instead of the property progressive_frame in CUVIDPARSERDISPINFO (which is unreliable).
